Trivia
In the Japanese version of the show, there was no Pink Ranger - hence there only being a Red, Black, Blue, Yellow, and White Shogunzord. The Cranezord was originally designed for the White Ranger (who, in the Japanese version, was female), and the Falconzord was an entirely different Zord. See more...

Mighty Morphin' Power Rangers trivia
Tommy has been more colours than any other Ranger. He has been the Green, White, Red, and Black Ranger.
Portions of every episode are from a Japanese version of the show. Almost every episode in series 1 was two thirds Japanese footage, just voiced over. Saban used this Japanese footage to save on filming its own.
Jason David Frank, who played Tommy, left the show in the episode because his powers had been stolen by the Green Candle. However, he had become the most popular member of the Power Team, despite the original plan being just to temporarily have him on the show. Saban received large amounts of letters daily requesting Frank be brought back. The company eventually gave in and brought Frank back in the episode "Return of an Old Friend." He was returned to Green Ranger status in part 2.
